摘要： The invention relates to a process for transmitting streaming digital content to a client device for access to digital content. The inventive process makes it possible, in particular, to apply an access control system to the protection of direct-mode video streams. The process also makes it possible to significantly improve the security and safety of the system, based on a periodic mandatory back-communication on the part of the client device.

摘要： Some embodiments are directed to a method and to a device allowing an access control system to be applied to the protection of streamed video. The inventive system and associated method allow an existing access control system of Marlin type to be used innovatively based on the execution of two successive operation phases allowing DRM rights to be acquired followed by the delivery of content and the decryption thereof.
